STEAM-TRAP.

To all whom it may concern:

Be it known that I, EMIL GorrERJE, citizen of the German Empire,residing at Leverkusen, near Cologne, Germany, have invented new anduseful Improvements in Steam-Traps, of which the following is aspecification.

The present invention relates to improvements in steam traps of thatcharacter which are adapted to collect and auton'iatically dischargewater of condensation that accumulates in a steam heating or similarsystem.

In the accompanying drawings; Figure l is a vertical sectional viewthrough a steam trap constructed in accordance with the presentinvention; Fig. 2 is a horizontal sectional view on the line 22 of Fig.1.

Referring to the drawings a designates the body of the trap which may beof cast metal and of any desired size and configuration. This body orreceptacle a is provided with a removable top or cover 7) secured tolaterally projecting ears or flanges on the body by bolts or similarfastening means.

The top 6 supports two pipes s, m which extend into the body a, theformer being connected by suitable means not shown, with the system ofpipes which is to be drained by the trap and the other pipe at servingto discharge the water collected in the trap in the manner hereinafterdescribed.

Mounted on the top Z) is a valve casing n which is arranged between twosections of the discharge pipe m so that the valve therein will controlthe passage of water from the trap. The stem 0 of this valve is attachedto a lever 29 which is fulcrumed at one end upon a standard Q risingfrom the top 6 and is of such length that its other end projects beyondthe opposite side of the trap body.

lVithin the body a is arranged a bucket or open-top float c which is ofless diameter than the interior of the body to provide an annular waterspace between itself and the wall of the body. A rod (Z connected at itslower end with the bottom of the float, extends upwardly through asuitable stufiing box 6 on the removable top or cover Z), and isconnected at its upper end with one end of a cord or chain 2'. The saidcord or chain extends around suitable guide wheels or rollers 71,supported by a cross piece 9 on an upright f and has its opposite endconnected Specification of Letters Patent.

with a weight or counterbalance Z. The lever 2) extends between suitablestops or tappets 1", 1 on the stem 7.: of the .weight Z, which isthreaded, to permit said tappets to be adjusted thereon, and connectedwith the flexible connector 2', which tappets are adapted to engage andactuate the lever as the weight Z rises and falls in accordance withmovements of the float c.

The inlet pipe 8 extends into the trap in position to discharge waterpassing therethrough into the space between the float and wall of thetrap body, while the discharge pipe m extends into the bucketlike floatc to a point relatively near the bottom thereof when said float is inits elevated position.

The operation of the parts hereinbefore described will be readilyunderstood. Normally the weight or counterbalance Z will operate to holdthe bucket c in the elevated position indicated by dotted lines and thetappet 1* will be in contact with the lever 72, thus maintaining thevalve closed. As the space between the bucket and casing a is filledwith water, the latter will overflow the upper edge of the bucket andwhen a sutlicient quantity has been collected in said bucket to overcomethe counterbalance Z, the bucket will descend into the position shown infull lines, where it may rest upon a suit able cushion or block u. Bysuch downward movement of the bucket c, the weight Z will be elevatedand the tappet 1* caused to shift the lever 39 into the position shown,thus opening the valve and allowing the water contained in the trap toescape through the pipe m.

When the water contained in the bucket c has been discharged to such anextent that the counterbalance Z again becomes efiective, the parts willbe restored to their previous positions, closing the valve.

It will be observed that the apparatus comprises a relatively smallnumber of parts and that all of those liable to need attention orrepairs, such as the valve, stutfing box a and parts connected with thelever 29, are located outside of the trap and thus are not only readilyaccessible, but are not exposed to the action of water or steam withinthe trap. By this construction also, it is possible to employ a valvehaving a maximum opcning so that the contents of the trap may be rapidlydischarged.-

Having thus described the invention, what is claimed is:

1. In a steam trap, the combination with a suitable receptacle, having aremovable top or cover, of pipes supported by the top for admittingwater of condensation to said vessel and conveying such water therefrom,a

lever fulcrumed on a support rising from the top, a valve casing mountedon the exterior surface of the top and connected with the dischargepipe, a valve therein having its stem connected with said lever, abucket-like float within the body of the trap and into which the end ofthe discharge pipe therein extends, a lifting rod connected with thefloat and extending through the top of the trap, and connections betweensaid rod and lever.

2. In a steam trap, the combination with a suitable receptacle, having aremovable top or cover, and pipes for admitting water of condensation tosaid vessel and conveying such water therefrom, of a valve casingsupported exteriorly of the trap and connected with the discharge pipe,a lever fulcrumed at one end on a support on the trap, a valve withinsaid casing having its stem attached to the lever, a bucket-like floatwithin the trap and surrounding the end of the discharge 'pipe therein,a lifting rod connected with the float and extending through the top ofthe trap, a standard rising from the trap and supporting suitable guidewheels or pulleys, a weight, a flexible connector extending from theweight to the lifting rod and passing over said guide wheels, and stopscarried by said connector and projecting across opposite edges of thevalve actuating lever adjacent its free end.

3. In a steam trap, the combination with a suitable receptacle, having aremovable top or cover, of pipes supported by the top and adapted toadmit water of condensation to said vessel and convey such watertherefrom, a valve casing mounted on the top and having therein a valvecontrolling the passage of water through the discharge pipe, a leverfulcrumed at one end on a standard rising from the top and extendingacross said valve casing, the stem of the valve in said casing beingconnected at its upper end with said lever, a float within the body ofthe trap, a lifting rod having its lower end connected to said float andits upper end extending through a stufling-box on the removable top, aweight or counterbalance, a flexible connector having one end attachedto said weight and its other end attached to said lifting rod, guidewheels or rollers for the connector supported by a standard rising fromthe top of the trap, and tappets connected with said flexible connectorand extending across the upper and lower edges of said lever,substantially as and for the purpose described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
